There are some things they are definitely NOT allowed to do like drive when drunk
There are other things I would HOPE they don't do like: do drugs, smoke ( I used to and the want stays with you!), binge drink, binge eat, binge anything! Join the army, ride motorbikes, dress like a chav (!) or for my daughter to dress like Jordon ( the tangoed lapdancer look)
But these are my bugbears, although I will be telling telling them to never drink and drive or get in a car with a drunk driver
